Vanderbilt University today announced a new collaboration with the nonprofit organization Climate Vault that allows the university to address the full.
Underground hydrogen storage could be the solution to bottlenecks in the current energy transition. This type of hydrogen storage poses a number of challenges that have not yet been adequately investigated. Utrecht University may have the answers. Dr Suzanne Hangx, a geologist at Utrecht University, explains, "To ensure safe and efficient hydrogen storage, we need to understand how underground reservoirs behave under the continuous injection and extraction of hydrogen fluid.

As the global energy demand continues to grow along with atmospheric levels of carbon dioxide (CO
2), there has been a major push to adopt more sustainable and more carbon-neutral energy sources. Solar/wind power and CO
2 capture - the process of capturing waste CO
2 so it is not introduced into the atmosphere - are two promising pathways for decarbonization, but both have significant drawbacks.
Solar and wind power is intermittent and cannot be deployed everywhere; CO
2 capture processes are incredibly energy-intensive. Both of these pathways have benefits, but each on their own does not present a viable strategy at the moment. However, a research team led by Dr. Faruque Hasan, Kim Tompkins McDivitt 88 and Phillip McDivitt 87 Faculty Fellow and associate professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, has uncovered a way to combine both of these processes together to increase the efficiency of both.

3D-printed gas diffusion layer for an electrochemical reactor, printed at the Cornell NanoScale Science and Technology Facility using two-photon polymerization. Study highlights promise of 3D printing for electrochemical reactors
April 30, 2021
Electrochemical reactors that can capture carbon dioxide and transform it into valuable products are a relatively new and promising technology for reducing greenhouse gas emissions. While many challenges exist to scaling up the technology, a new study highlights the benefits of using 3D printing, also known as additive manufacturing, to significantly improve cost, yield and efficiency.
In electrochemical reactors like those that were studied, gaseous carbon dioxide travels through a porous gas diffusion layer for distribution to the catalyst, where it dissolves into a liquid electrolyte and converts to various products like fuels, lubricants and polymers. Using additive manufacturing to rapidly prototype
